Our themes are very short on their own strings, so we don’t currently have a system set up for S themes to load translations. It’s a bit of an issue just because the current translation loading system is designed to work with module config, which isn’t available to the themes. In some ways, the themes aren’t a particularly good match for Zend’s module system, since we want to only load the one we need for a particular site.

A crummy workaround that would work would be to have a module that just loads the translations, but that’s clearly far from ideal.
